KRP-C-4000SP

工业与电气保险丝 4000A

* Industry’s only UL Listed and CSA Certified fuse with a 300kA interrupting rating that allows for simple, worry-free installation in virtually any application. * Fast short-circuit protection with time-delay performance provide ultimate protection. * Consistent 2:1 ampacity ratios for all Low-Peak fuses make selective coordination easy. * Time-delay for close sizing load. * Current-limiting action of the fuse generally affords considerable reduction in bus bracing. * All-purpose silver-linked fuse for both overload and short-circuit protetion for high capacity systems mains and large feeders. * O-ring seals maximize pressure build-up during current-limiting action and ensure filter retention. * High-grade silica sand filler accelerates response of fuse to short-circuits by having quenching effect on the fuse arc. * 99.9% pure silver links provide low watt loss with low operating temperature on normal current levels and minimizes total clearing I2t fault energy left-through.
